Intially, the economy is in equilibrium at Point E.
SHORT - RUN EFFECT:
A rise in the federal government spending on the national defense increases the flow of money into the economy. This will increase the purchasing power of the people inducing them to increase their demand for goods and services. This will increase the aggregate demand and consequently the AD shifts to the right from AD1 to AD2.
The new equilibrium is at point E1 where both output and prices are higher.
LONG-RUN EFFECT:
In the long run, in order to re-store the equilibrium at full
potential level of output, the AS curve shifts to the left from AS1
to AS2 so much so that it intersects the New AD and the LRAS curve
at point E2.
The economy is back to the potential level of output with more inflation.
